An officer was treated at a Hartford-area hospital Thursday morning and released after a violent collision with an SUV carrying a woman and two children, police said.

The crash on Tunxis Avenue, or Route 189, sent the police SUV careening off the road into heavy equipment and a utility pole wire, which forced the vehicle on its side, police said. The other SUV, a Toyota Highlander, also went off the road, its driver-side doors bashed in.

The officer, who police on Friday said was Officer Jonathan Sykes, was discharged from St. Francis Hospital and Medical Center after being treated for minor injuries. Neither the driver of the Toyota nor the children — who had been in car seats — had signs of physical injuries, police said; the driver, Marline Adesokan, 40, of Bloomfield, was taken to Hartford Hospital and the children to Connecticut Children's Medical Center as a precaution.

"He's very lucky," Capt. Stephan Hajdasz said of Sykes, who had superficial injuries from shattered glass and air bag. He has been with the force since February of 2015.

The police SUV, which was purchased in 2016, was totaled, he said.

According to police, the crash happened shortly before 8:10 a.m. near Mills Lane, when Sykes was driving the marked SUV south to the scene of a reported altercation involving a man and a woman. His emergency lights and siren were on.

The woman driving the Toyota, also south on Tunxis Avenue, started to turn left as the officer was passing her on the left, and the two SUVs collided, Hajdasz said. The patrol car went off the road and crashed into a backhoe and utility pole support wire on Mills Lane, flipping onto its passenger side.

The intersection with Mills Lane was closed while members of a regional accident reconstruction team gathered evidence, photographed the SUVs and took measurements.

No enforcement action has been taken, Hajdasz said Friday; the crash remains under investigation.
